Suppose the Remedies Pharmaceuticals Company develops a new drug designed to prevent a new strain of the flu. The company states that the drug is more effective for women than for men. To test the claim, a random sample of 145 women and a random sample of 214 men are obtained from a large population of volunteers who were registered with the company for medical trials. At the conclusion of the study in September the number of women and men who caught the flu was recorded, and a 95% confidence interval for the difference (women - men) in the proportion of women and men who caught the flu was found to be ( - 0.263, - 0.029). (A) Interpret the 95% confidence interval in the context of the problem. Enter your answer below. This question will be marked by your instructor. (B) If we decided to calculate a 99% confidence interval instead, would the resulting interval be narrower or wider than the 95% confidence interval? In the same answer box below state NARROWER or WIDER, then explain your answer. This question will be marked by your instructor
